To a/ZZ whom, 7115 may concern:

Be it known that we. LUTHER E. ROBY and CLARENCE A. PATTIsoN, citizens of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Grain- Drills; and we do hereby declare that lthe following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains toV make and use the same.

This invention has reference to grain-drills, and relates particularly to a disk furrowopener and a boot or conductor having a pivotal connection with the said disk.

The invention has for its further object the manner of mounting the disk or furrow-opener on the drag-bar and the boot or conductor on the disk, one object being to provide means for positively preventing the entrance of dirt or grit in the bearings thereof.

The invention consists of a disk furrowopener supported in a suitable manner on a drag-bar, a conductor formed with a boot and having a shoe or arm, the forward portion of the said arm being pivotally attached to the bearing of the disk, the arrangement of the disk and boot being such that the arm of lthe boot connects with the bearing of the disk upon the convex face thereof.

The invention consists, further, in the provision of details more particularlyT set out in the following description, claimed in the appended claims, and illustrated in the accompanying drawings, in which- Figure l is a side elevation of a supportingframe and ground-wheels in dotted lines and showing the disk and boot supported by the boot to the disk giving an independent move- Y ment to the boot, whereby the same will travel along the base of the furrow and always on a line with the lower cutting edge of the disk.l Fig. 2 is a plan view of a drag-bar and disk and boot supported thereby. Fig. 3 is a vertical cross-section, enlarged, through the dragbar, disk, and bearing therefor on the dragbar and showing the pivotal connection between the bearing of the disk and shoe or arm of the boot. Fig. is a transverse section,

enlarged, through the bracket, forming a support for ,the disk and boot on the drag-bar, showing a scraping edge of the bracket on the convex side of the disk. Fig. 5 shows indetail two opposite end views of the tubular bearing member connected with the drag-bar. Fig. 6 is a side elevation, enlarged, of the devices shown in Fig. l, omitting the supporting-frame and the connections from the dragbar therewith. Fig. 7 is a view similar to that seen in Fig. 6, but looking at the opposite side of the device; and Fig. 8 is a cross-section taken on the line X X of Fig. .6.

It is our aim in the present invention to provide in combination with adisk furrow-opener and its support, the drag-bar, a grain-conductor which shall have a pivotal connection with the disk and its support to be independently movable or be governed by the rise and fall or raising ory lowering of the disk and to follow in the wake of the disk and in the furrow made thereby to deposit seed and grain in the deepest cut portion of the said furrow. This may be accomplished in addition to the pivotal connection with the disk by permitting the boot to drop or follow the furrow; opener by its own weight and be raised through suitable engagement of the dragbar with means attached to the boot, providing a pullingspring which shall be attached to the drag-bar and to the boot, so that as the dragbar is lowered to depress the disk into the ground the boot will oscillate on its pivot and be drawn down into the furrow cut by the disk.

In the drawings, l denotes by dotted lines the usual supporting-frame for grain-drills of the character specified herein, the same suitably carried by an axle 2, which is connected to the ground-wheels 3, also shown in dotted lines. The frame supports the ordinary seedhopper 4, in which is carried suitable seed or grain feeding devices, (not shown,) and connected with said hopper and the devices specilied is shown the grain-spout 5 and the feedtube 6, all of which are shown in dotted lines. The parts of the frame-supports, wheels, and feed-spouts are shown in dotted lines, as they form no part of the invention herein, and any of the well-known devices of this character may be provided.

7 denotes a drag-bar of suitable length connected with a head 8, which has a pivotal connection with a rod or spindle 9, suitably supported from the main frame l. At a suitable point on the body of the drag-bar 7 is iixedly IOS IIO

attached a` bracket or support 10, which depends from the said drag-bar and is provided with a disk-shaped portion 11, through which is an opening 12, and upon the rear face of the bracket and the disk portion thereof the same is provided with the annular ring 13, projecting laterally therefrom, with its inner and outer faces preferably tapered. That portion of the bracket or disk portion within the annular projected ring 13 is provided with the depressed annular groove 14.

The disk which has been referred to is indicated as 15 and is similar to disks used in machines of this character` having, concave and convex facesand provided with the enlarged central opening 16, which is adapted to be slipped over the outside of the ring 13 when aiiixin'g the disk to the drag-bar. (See Fig. 3.) In mounting the disk attention is called to the fact that the convex face of the disk is placed in juxtaposition to the inner face of the bracket 10 of the drag-bar. To the inner or concave face of the disk is attached a casing 17, formed with the tubular extended portion 18, the outer periphery of which is threaded and the inner face suitably tapered. The outer face of the casing is provided with an annular depressed groove 19, which is adapted to slip over the annular ring 13 of the bracket and to revolve thereon.v The bearing for the said disk and its casing 17 is a tubular member 20, having a tapered construction and provided with the outer annular flange 21, which is adapted to be seated in the annular groove 14 of the bracket and having a locked relation with the bracket by means of a lug or projection 22 on the bracket adapted to be seated in a notch 23, cutin the ange 21. The end of the tubular member 2O is closed by a cap-plate 24, having a beveled face engaging a corresponding beveled portion of the member and locked against rotation by means of -a lip or lug 25, formed on the capplate and engagingadepression 26 in the matching edge of the member. The cap-plate and the member are secured to the bracket 1() by means of a bolt 27, passed through the cap-plate 24, the member, and the opening 12 in the bracket. A nutl 28 is adapted to engage the end of the bolt for holding the same in place. The bolt and nut serve the further function of securing a collar 29 against the outer face of the bracket, as seen in Fig. 3, with the reduced portion of the collar bearing in a recessed portion 30 of the bracket, the collar being provided with a flange 31, leaving an open space between the iange of the collar and the face of the bracket for a purpose to be described. The cap-plate and the end of the bearing 20 are incased in a dust-proof cup 32, which has a screw connection with the threaded portion of the casing 18.

The boot or conductor to which attention has been called is indicated as 33, is provided with the inner tubular openings into which extends the tube 6, and by means ot' which seed or grain is directed from the hopper to the ground. The boot has attached thereto or cast integral therewith the forwardly and upwardly carried shoe or arm 34, the forward end of which is provided with an opening by means of which the shoe or arm is slipped onto the reduced portion of the collar 29 before the said collar is fixed into position,

as seen in the tigures, by the nut 28, the arm 34 where it connects with the collar filling' the space between the ange of the collar and face of the bracket to turn on the collar, which it is apparent forms a pivot for the end of the said arm, the lower portion of the arm where it merges into the boot being provided with the point 35, which rides on the base of the furrow cut by the disk and insures that all grain or seed passed through the boot will lodge at this point. The arm 34 is carried upon the convex side of the disk and is provided with the scraping edge 36, engaging the face of the said disk. There is provided additional scraping means for the outer face of the said disk by curving theV rear edge of the bracket 10 in against the disk, as at 37, more clearly seen in Fig. 4 of the drawings.

The drag-,bar 7 extends beyond the bracket 10 and across the face of the disk and the boot 33, and to the bar at a point, preferably 38, is connected a pulling-spring 39, the upper end of which is adjustably connected to a bracket 40, secured to or forming a part of the upper end of the. boot 33. rDhere is further attached to the d rag-bar and at or near the outer end thereof a rod 41, which at its upper end passes through the usual swivel-casting (not shown) carried by an arm 42, extending from and secured to a shaft 43, which is arranged to be rocked in its bearings for the purpose of raising or lowering the arm 42 for raising the disk 15 from the ground or depressing the same therein. lt is apparent that if the arm 42 is lowered the drag-bar which is connected thereto and the disk supported by the drag-bar will be lowered somewhat, as shown in dotted lines in Fig. 1, governed by the swinging motion which is imparted to the arm 42.

The lowering of the drag-bar 7 through the spring 39 will draw the bootv downwardly, which being pivoted to the disk will drop into the position seen in dotted lines, Fig. 1. By the pivoting of the arm or shoe of the boot to the disk the lsaid boot is adapted to rise and fall independently ot' the said disk or with the same and in working' position remains with its lowermost portion traveling in the wake of the disk and on a level with the lowermost cutting edge of the said disk.

The rod 41, as usual in mechanisms of this kind', carries a spring 44, capable of being acted upon by the arm 42 for exerting more or less pressure upon the disk in the ground. We have provided for doing away with the IOO use of the spring, if desired, by securing two pins or studs to the boot (indicated as 45 and 46) above and below the drag-bar. (See Fig. l.) In this way when the disk is depressed into the ground it is adapted that the boot and shoe of their own weight will drop to the position seen in Fig. 1, the pin 46 serving as an engaging point for-the drag-bar when rais-..

ing the disk and the pin 45 serving as an engaging point for the drag-bar when the disk is depressed should the boot and shoe fail to correspond, all of which it is believed will be understood.

From the foregoing description of the device it is believed the arrangement. construction, and operation ofthe devices will be fully understood. It is well, however, to call attention to the salient features of the device, also to have it understood what modications and changes are contemplated in the construction. rIhe shoe or arm of the boot, as the same has been termed, is in reality a furrow-opener acting supplementary to the cutting edge of the disk to provide for and to make way for the lowermost portion of the boot in depositing the seed or grain in the furrow. By pivoting' the shoe to the center of the disk the boot travels behind the cutting edge thereof` and is independently movable, so that in following the irregularities of the ground the disk and shoe or boot may rise and fall independently of each other and without disturbing the other. Were the shoe and boot fixedly attached to the disk or its support it would act in unison with the rise or fall of the disk and the functions here attainable be destroyed.

Ve wish it understood that while we have shown one form of spring other and various forms may be used with as good results, and under certain conditions it may be advisable to make some suitable change. This is also true of thedisk which we have described and shown as a concavo-conveX disk. Other forms may be substituted with as good results, and while we have shown the boot pivotally attached through its shoe with the disk we have anticipated that the connection may be made in various ways and leaving the shoe free to travel behind the disk or, if desired, omit the disk and substitute some other form of furrow-opener and pivot the shoe to an oscillating support, such as the drag-bar or equivalent member, and we do not wish to be confined to the details as herein set forth, but to include such other modifications and equivalents as shall come within the scope of the claims.
